LEVELER FOR FORMS OF TYPE.

Specification of Letters Patent.

To al?, whom it may concer-1c:

Be it known that LARTHUR SAMUEL ALLEN, a citizen of the United States,residing at Brookline, in the county of Norfolk and State ofMassachusetts, have invented an Improvement in Levelers for Forms ofType, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresenting like parts.

This invention has for its object the production of a leveler or deviceto be laid upon the face of type or plates keyed in a form and which maybe struck by a mallet or other device to bring the type or plates to thesame level preparatory to the production of stereotypes or printing.Heretofore this work has been done by laying a wooden block on the faceof the type keyed in the form and striking the block with a mallet.These blocks, that they may be strong enough to stand up under the blowsof a mallet and not break, are made of hard wood of considerable sizeand thickness, are consequently heavy to handle, and the face of theblock brooms and becomes disintegrated, so that another block has to becalled into play or the face of the block be planed off.

In my aim to produce a device for leveling type, of less weight, andconsequently easier to handle, and possessing greater durability thanthe usual wooden block, I have provided the leveler or device to beherein described, it comprising a body having a face composed of a layerof tough non-metallic non-ligneous close-grained material-such, forinstance as compact iiberoid or so-called leather-board or vulcanite.The top of the body referred to is also protected by a like substancethat will not be disintegrated by the blows of a mallet or hammer.

Figure 1 ,in side elevation,partly broken out, shows a leveler or deviceembodying my invention; and Fig. 2 is a top or plan view thereof.

The device comprises a body A, having the form of a parallelogram; butthis is immaterial. As is plainly illustrated in the drawings, there isa deep broad groove a' running around the entire perimeter of the bodyA. Where the body is rectangular or has parallel sides, it is obviousthat this groove may be made to extend throughout only two of itsparallel sides, if so desired. So, also, where the body has a circularor elliptical top surface the groove may be made only at opposite sidesthereof. This groove is used to supplement the top surface as a handleto insure a reliable grip on the block when it is being moved about. Thebody has secured to it by suitable devices a., which may be screws, aface B, composed of a compact layer ofiiber oid or so-calledleatlier-board, vulcanite, or other equivalent non-metallic nonligneousmaterial.

The materail entering into the face will be hard enough to stand upunder the blows transmitted through the leveler onto the type or plateskeyed together in the form, but not hird enough to batter and injure thetype or ates.

The top of the body is shown as provided with a top facing C, which maybe of the same material as the bottom face B, said top face being heldconfined on the body by de? vices shown as screws b, the heads of whichare represented as countersunk or standing in spaces at the upper sideof said top face C.

I intend to include in my invention under the terms detachable face anddetachable top any material such as named or their known substitutesother than metal or wood, and while I prefer that the leveler should bethe shape of a parallelogram, as represented, yet the particular shapeof the body and the face B are not essential so long as the acting partof the face represents a plane surface.

A leveler such as herein described and illustrated possesses greaterdurability, is lighter in Weight, and smaller in area than usual devices used for this purpose and commonly designated in the trade astype-planers.7

I-Iaving described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A type-leveling block comprising a body portion having a deep broadgroove on its opposite edges or sides by which to hand-mw In testimonywhereof I have signed my nipulate the block, and having parallel uppername to this specification in the presence of 1o and lower surfaces, anda detachable facing two subscribing witnesses.

for each of said surfaces disposed in parallel planes, said facing beingformed of non-me ARTHUR SAMUEL ALLEN' tallic, non-ligneous material toreceive the /Vitnesses:

same to the type without injury. MARGARET A. DUNN.
